BIM and Building Performance Simulation – From Single Building to Urban Scale Ms. Michelle M Farrell, Head of the European Division Integrated Environmental Solutions, Limited HKIBIM-CIC BIM Conference 2015 Date: 19-Nov-2015 (Thu) Time: 9:00 a.m. – 5:00 p.m. Venue: Theatre 2, Level 1, Hong Kong Convention and Exhibition Centre, Wan Chai, Hong Kong Organizers: The Hong Kong Institute of Building Information Modelling (HKIBIM) http://www.hkibim.org Co-organizer: The Construction Industry Council http://www.hkcic.org The HKIBIM - CIC BIM Conference 2015 is the 6th Annual Conference organized by the Hong Kong Institute of Building Information Modelling (HKIBIM). It is the premier annual event for experienced AEC professionals to demonstrate the practical use of Building Information Modelling (BIM) processes using real cases. The speakers will illustrate lessons learned in practical projects so that others can improve their efficient use of BIM and advance practical knowledge.

12. But how can we understand our building in
the context of a larger city or masterplan ?

13. Combining and building smarter models that
contain all of the data we need, then performing
an analysis that truly considers context

19. District 3 – Roofs > 25,000 sq. ft.
Part of District 3

20. PV/Solar potential
• Measured average solar radiation over 11 sites = 4.2-4.6
kWhrs/m2/day.
• Simulated value = 4.7 kWhrs/m2/day
• PV potential for 25,000 sq. ft. roof assuming 15% PV
coverage = 72,000 kWhrs of electricity/annum
